Number oi segments 49. Length about 120 mm. 



A single $ specimen from Madras (Jordan coll.) 



This species may be readily recognised by its long hooked caudal 

 process, and the tubercular ornamentation of the tergites. This last 

 character is one by which it may be at once distinguished from 

 %). thurstoni, which in other respects it seems to approach. 



Spirobolus greeni, sp. n. 

 ( PI. i, figs. 10, 10a. ) 



Colour (in alcohol) ; head infuscate, antennae infuscate, paler at 

 the base ; coUum inf uscate with paler borders, rest of the somites 

 bluish slate-grey, with a single large, wide, fulvous spot on the pos- 

 terior half on each side of the middle line of the back, anal somite 

 fulvous, slightly fuscous above ; legs wholly fulvous. 



Head and/«ce smooth, the latter marked with a longitudinal sulcus, 

 and with two pores on each side ; antenncB very long for the genus, 

 reaching to about the 4th or 5th somite ; eyes large, widely separated, 

 composed of about 50 well defined ocelli. 



Somites without scobina ; coUum punctulate and rugulose, not pro- 

 duced so low as the inferior extension of the second, the apex obtusely 

 rounded, with the margins nearly straight, i.e., only slightly convex, 

 the apex and the anterior margin as high as the eye defined by a 

 sulcus ; the posterior half of the other segments much higher than the 

 anterior, marked laterally as high as the pores with distinct sub-parallel 

 longitudinal striae, the upper part above the pores marked with punc- 

 tures and irregularly scattered, abbreviated, anastomosing striae, form- 

 ing an obscurely reticulated pattern ; the anterior portion marked 

 above with circular or elliptical areas, and below with oblique more or 

 less curved striae which are continuous with the striae of the posterior 

 portion ; poirs situated above the middle of the sides, in the posterior 

 half of each somite the first a little lower than the second. Anal somite 

 punctulate, the upper part produced into a short, blunt, straight, 

 slightly compressed caudal process, projecting a little beyond the 

 margin of the valves ; valves convex, strongly but narrowly compress- 

 ed, the upper angle not compressed and a little produced; sternite 

 posteriorly rounded and angulate. 



Legs slender, elongate, with a single seta on the lower edge of each 

 segment. ■
